Riser termination device

Abstract

A bath tub solids container for containing solids separated from cracked product vapors produced in a riser reactor and issuing from a separator. The bath tub solids container receives and contains solids from the separator, has a collar which fits around the riser reactor to keep the solids from contacting the riser reactor, an aeration device for fluidizing the solids within the container and an outlet for the solids.

1. A bath tub solids container for containing solids seperated from cracked product vapors produced in a riser reactor and issuing from a separator, said bath tub solids container comprising: a containment means for receiving and containing solids from said separator; a collar for fitting around said riser reactor and keeping said bath tub solids from contacting said riser reactor; an aeration means for fluidizing solids cotained in said containment means; and a fluidized solids outlet means for allowing fluidized solids to exit the containment means. 
     
     
       2. A bath tub solids container as defined in  claim 1  wherein said bath tub device aeration means comprises steam nozzles for injecting steam into said containment means. 
     
     
       3. A bath tub solids container as defined in  claim 2  wherein said bath tub device fluidized solids outlet means comprises at least one catalyst distributor overflow slot and one catalyst drain point.
